Description
This security bulletin contains information about 8 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-23772)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the Rat.SetString(0 function in math/big. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Incorrect authorization (CVE-ID: CVE-2022-23773)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists within cmd/go, which can misinterpret branch names that falsely appear to be version tags. This can lead to a situation where an attacker can bypass implemented security restrictions and perform restricted actions, e.g. create tags when access was granted to create branches only.
3) Unchecked Return Value (CVE-ID: CVE-2022-23806)
CWE-ID: CWE-252 - Unchecked Return Value
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked return value within the Curve.IsOnCurve() function in crypto/elliptic. A remote attacker can force the application to incorrectly return true in situations with a big.Int value that is not a valid field element. As a result, an attacker can modify application flow, which can lead to unauthorized data modification or denial of service.
4) NULL pointer dereference (CVE-ID: CVE-2022-29224)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the GrpcHealthCheckerImpl. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2022-29225)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Incorrect Implementation of Authentication Algorithm (CVE-ID: CVE-2022-29226)
CWE-ID: CWE-303 - Incorrect Implementation of Authentication Algorithm
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to to bypass authentication process.
The vulnerability exists due to the OAuth filter implementation does not include a mechanism for validating access tokens. A remote attacker can bypass the authentication.
7) Buffer overflow (CVE-ID: CVE-2022-29228)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when oauth filter calls continueDecoding(). A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
8) Out-of-bounds read (CVE-ID: CVE-2022-31045)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the Ill-formed headers. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.
